SPECIFICATION forming part of Letters Patent No. 695,744, dated June 14, 1898.

Application filed April 3, 1897. Serial No. 630,581. (No model.)

To all whom, it may concern.-

Be it known that I, iVILsoN E. PORTER, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Hammers for Striking-Clocks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure l, a face view of the outer plate of a clock-frame, illustrating my improved hammer applied thereto; Fig. 2,a perspective view of the hammer detached; Fig. 3, a sectional view through the hub.

This invention relates to an improvement in the hammers for striking-clocks,'and par-' ticularly to that class in which the hammerarm is connected with a hub which also carries a lifting-finger and a stop. As usually constructed the hub is formed with three openings and the hammer-arm, lifting-finger, and stop are formed from wire, the ends of which are inserted in the holes of the hub, where they are retained by solder. In thus inserting and securing the parts they are liable to be thrown out of proper alinement, and in the bending necessary in adjusting the movement the parts are liable to become detached. v

The object of this invention is to construct the hammer-arm, the lifting-finger, and stop from a single piece of sheet metal and secure it to the hub without solder; and the invention consists in the details of construction which will be hereinafter described, and particularly recited in the claim.

The hammer-arm A, lifting-finger B, and stop 0 are formed integral with a plate D, from which they are bent to stand in the position necessary for operation, according to the movement to which they are to be applied. In the outer end of the plate D is an opening E to receive the reduced inner end F of a hub G, which has a central opening H, whereby it may sit over a stud I on the case J in the usual manner. The plate D is set over the reduced portion of the hub and that reduced portion upset, so as to interlock the plate with the hub and firmly secure the two together, and this is the preferred form, although other methods of securing the plate to the hub may be employed. the plate is secured to the hub the hammerarm, lifting-finger, and stop are positively fixed with relation to each other and, being formed in a press, require no adjustment in assembling the clock, as they must necessa- 'rily stand in proper position with relation to the frame, so that each performs its proper function.

I am aware that it is not broadly new to form parts of the lockwork of striking-clocks of sheet metal nor broadly new to combine in such parts a plurality of arms formed integral with each other from the same piece of sheet metal and taking the place in the lockwork of a plurality of wires. I am further aware that it is old to adjustably mount a hammer upon a long hammer-arm, so that the hammer may be shifted in position with respect to the gong whichit strikes. I do not, therefore, broadly claim a sheet-metal lockwork part formed from a single piece of sheet metal and combining a plurality of lockwork members; nor do I broadly claima hammer adjustably mounted upon a long hammerarm.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

A sheet-1n etal combination part for the lockwork of striking-clocks, the said part comprising a body portion, a long hammer-arm formed integral with the said body portion with which it is parallel, a lifting finger formed integral with the said body portion and bent inward at a right angle thereto, a stop also formed integral with the said body portion and bent inward at a right angle thereto in the same direction as the said liftingfinger, an independently formed hammer mounted upon the said hammer-arm, and an independently-formed hub rigidly secured by upsetting its reduced inner end, to the outer face of the said body portion, and providing a long bearing for the stud on which the combination part is hung, and 011 which it oscillates.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
